Anonymous users2024-01-23240 kilowatts need three-phase four-wire power supply, the main line needs at least one 240 square aluminum wire, or 185 square copper wire, to use 630A molded case circuit breaker or universal circuit breaker, the air opening is not so large.
Such a large load can not use a power supply, should be based on the actual situation of multiple power supply, one is convenient maintenance of a power outage has little impact on other equipment, and then to reduce the failure rate, and there is a lot of cost reduction, because the thicker the single strand wire diameter, the smaller the current carrying capacity per unit area.
You need to tell you how much equipment you want to use, such as how big the pot is in the kitchen, how big the freezer is, what kind of electric oven, induction cooker, etc., can help you calculate how big the wires to use.
Is it because the voltage of the power supply line has decreased? Or is it that too many electrical appliances cause the voltage and current to decrease?

Hello: 1. First of all, how much power do you need for an induction cooker? Cooking or stir-frying or stewing? >>>More
